Parameters

Required: one of symbol, isin, for example isin=IE00B4L5Y983.

Name	In	Type	Required	Description
symbol	query	string	one of symbol, isin	ETF ticker symbol (e.g., `IWDA.AS`). Provide exactly one of symbol or isin; clear the ISIN example before using a symbol.
isin	query	string	one of symbol, isin	ETF ISIN code (e.g., `IE00B4L5Y983`, iShares Core MSCI World UCITS ETF). Provide exactly one of symbol or isin. Example `IE00B4L5Y983`
view	query	string	no	Holdings view. `display` (default) weighs every row by market value, so a fund sums to ~100, with cash, Treasury bills and money market funds as their own rows; swaps and futures (no market value) and negative cash rows are left out. `raw` lists every row and keeps the issuer's exposure weights, so derivatives count at notional (a 3x fund ~300) and swaps list their counterparty. Plain ETFs are the same in both views. Unrecognized values fall back to `display`. One of `display` `raw` Default `display`
limit	query	integer (int32)	no	Maximum number of results to return (default 100, max 1000) Default `100`
offset	query	integer (int32)	no	Number of results to skip for pagination (default 0) Default `0`
cursor	query	string	no	Opaque cursor for cursor-based pagination. When provided, returns results after the cursor position. Takes precedence over offset.

symbol query

ETF ticker symbol (e.g., `IWDA.AS`). Provide exactly one of symbol or isin; clear the ISIN example before using a symbol.

isin query

ETF ISIN code (e.g., `IE00B4L5Y983`, iShares Core MSCI World UCITS ETF). Provide exactly one of symbol or isin.

view query

Holdings view. `display` (default) weighs every row by market value, so a fund sums to ~100, with cash, Treasury bills and money market funds as their own rows; swaps and futures (no market value) and negative cash rows are left out. `raw` lists every row and keeps the issuer's exposure weights, so derivatives count at notional (a 3x fund ~300) and swaps list their counterparty. Plain ETFs are the same in both views. Unrecognized values fall back to `display`.
